Nitrogen and phosphorus removal filter and method for trioxygen microorganisms

Abstract

The invention discloses a nitrogen and phosphorus removal filter and method for trioxygen microorganisms. The filter comprises a box body, and a water inlet and a first water outlet of an trioxygen generator are respectively formed in the lower part and the upper part of the box body; a denitrification treatment area and a nitrification treatment area are sequentially arranged in an inner cavity of the box body from bottom to top; anaerobic and anoxic microorganisms are arranged in the denitrification treatment area; aerobic microorganisms are arranged in the nitrification treatment area. Themethod comprises the steps: introducing circulating wastewater into a treatment container simultaneously containing anaerobic and anoxic microorganisms and aerobic microorganisms, carrying out denitrification reaction on phosphorus in the circulating wastewater by virtue of the anaerobic and anoxic microorganisms, and carrying out nitrification reaction on ammonia nitrogen and nitrite in the circulating wastewater by virtue of the aerobic microorganisms. According to the nitrogen and phosphorus removal filter and the nitrogen and phosphorus removal method for the trioxygen microorganisms, ammonia nitrogen, nitrite, phosphorus and other substances in the wastewater are completely treated, the treated water can be reused as culture water, and water resources are saved.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a filter for nitrogen and phosphorus removal by three oxygen microorganisms and a method thereof. Background technique [0002] Since the reform and opening up, my country's aquaculture industry has entered a period of rapid development. Followed by a large amount of farming waste, such as livestock and poultry and wastewater generated in the process of aquaculture. Aquaculture wastewater is mainly autologous wastewater, which contains a large amount of ammonia nitrogen, bacteria, dissolved organic matter, undigested feed, etc., and the discharge volume is huge. In order to improve economic benefits, some farmers cause aquaculture wastewater to be discharged randomly, which has a serious impact on the environment and also endangers aquatic products. At present, the vast majority of aquaculture wastewater is directly discharged into the environment, and there is a lack of ef...

AI Technical Summary

Problems solved by technology

However, the denitrification process of wastewater must rely on the two processes of nitrification and denitrification. Aerobic microorganisms can only perform nitrification, so the denitrification function cannot be realized, and the treatment of ammonia nitrogen, nitrite and other substances in aquaculture wastewater is not complete. The nitrogen content of the treated water body does not decrease significantly, and the water body cannot be recycled
